@chlopzewsi It's not a hack. The preset system is designed to do a specific job which doesn't include handling sample maps.

On a large project, like the woodwind library I show, it would be horrible if the preset system controlled the sample maps. Because every time I add a preset I would have to go into every sampler and change the sample map manually. Doing it programmatically is much more flexible. On a small project with only one sampler it might seem like a lot of extra work but it can be setup in 5 minutes and once you've written the code you don't need to write it again, just copy and paste.
